/**
 * A utility composable providing core logic for flattening complex nested object rows,
 * resolving deeply nested dot-notation object paths, auto-detecting array or foreign key relations,
 * and formatting cell values for rendering inside the main data table view.
 * @example
 * ```ts
 * const { flattenKeys, getColumnValue, formatCellValue } = useNctTableFormat()
 * const row = { id: 1, user: { profile: { firstName: 'John' } } }
 * const columns = flattenKeys(row) // ['id', 'user.profile.firstName']
 * const value = getColumnValue(row, 'user.profile.firstName') // 'John'
 * ```
 * @returns An object containing table formatting, row flattening, and relationship detection helpers.
